(See Fig. 5.) The vaporizing- 4o will be pointed out in the claims at the end of tube 2 at its upper end is provided with an anthis specilication. nular flange 8, through whichare made aplu- 9o Figure l is a vertical section and elevation rality of holes or openings 9 for supplying air of a singlemantleincandescent hydrocarbonto the flame issuing from the small vapor-outlamp embodying this invention; Fig. 2, a lets o, and below the iange 8 the vaporizing- 45 transverse section on the line 2 2, Fig. i, tubeis provided withasecond liangel0,which looking down; Fig. 3, a detail in plan to be is of substantially thesame size as the flange 8 95 referred to; Fig". 4, a vertical sectional deand is separated therefrom by an air-space 12, tail of the oil and needle valves; Fig. 5, a the flange l0 acting as a shield for the heatmoditication to be referred to; and Fig. 6, a ing-jet. The vaporizing-tube extends up into the inner tube aand its upper surface is substantially on a line with the air-supply tubes e, so that the vapor issuing from the vaporizer through a substantially small or min ute opening in the upper surface of the tube 2 may be commingled with the air drawn in through the supply-tubes c. The mixture of air and vapor passes up through. the tube c into the chamberf, and the upwardly-moving mixture of vapor and air is arrested by the wall g and caused to pass down said chamber outside of the tube a and into the chamberj through the outlet-openings 'L'. The mixture of air and vapor fills the chamberj, and the larger quantity or greater volume passes up the chamberj and out therefrom through the openings n into the chamberp,from whichv it passes through the foraminous cap q and is ignited, thus raising to incandescenoe a mantle t, supported above and in line with the outlet-mouth of the burner. A smaller volume or portion of the mixture of air and vapor passes from the lower end of the chamberg through the outlets or openings o, and, being ignited, forms a heating-jet, which surrounds the upper portion of' the vaporizer, thus heating the same sufficiently to insure proper vaporization of the oil in the Vaporizing-tube.

Owing to the proximity of the small vaporoutlets o to the vapor-inlet openings i for the chambery', the supply of vapor for the heating-jet is assured and liability of the heating-jet being extinguished before the main flame is extinguished is avoided, thus obviat- .ing the danger of fires caused by the heating-jet being extinguished by a deficient supply of vapor to maintain it, thereby cooling the vaporizer and allowing the oil to be forced up into contact with the hot mantle.

The supply of vapor to the burner is controlled by a needle-valve 20, having its lower end attached to the oil-valve 2l, so that both valves may be moved simultaneously in the samedirection. Theoil-valve21ismadetapering at its upper end and coperates with the outlet-passage 22 for the valve-chamber23,(see Fig. 4,) and the said valves may be actuated, as shown, by a pin 25, extended into an opening 26 in the valve 2l and attached to a valvestem or actuating-rod 27, which is extended into the valve-fitting 4 substantially at right angles to the movement of the valve 21, the said rod or stem being supported by a sleeve 28, attached to the valve-Iittingand provided with a packing-nut 30 at its outer end. The needle-valve 20 may and preferably Will be screw-threaded at its lower end to engage a v screw-threaded socket in the end of the oilvaporizer is shut off, While at the same time permitting the discharge of vapor to be regnlated.

One of the features of this invention consists in preventing the oil-valve being moved by the pressure of the oil, which if permitted to take place would seat the valve and shut 0E the supply of vapor to the burner, and this result is accomplished, as herein shown, by providlng the valve-actuating rod or stem 27 with screw-threads 32 at its inner end, (see dotted lines Fig. 4 and full lines Fig. 6,) Which engage a threaded socket 33, extended into the valve-fitting from one side of the valvechamber 23. By an inspection of Fig. 4 it will be seen that the oilvalve,which is moved by the pin 25 on the rod or stem 27, is locked against longitudinal movement except when actuated by the rotary movement of the rod or stem 27, as the movement of the valve is in a direction transverse to the said stem or rod, which is given only a half-turn in opposite directions to close and open the oil and needle valves. The oil-valve 2l is made a little smaller in diameter than the valve-chamber for the passage of oil to the vaporizer when the valve is open.

The single-mantle lamp herein shown may receive its supply of oil from the font 7, (see Fig. 5,) containing oil and air under pressure,` or it may receive its oil from a pipe 34, connected with a supply-tank (not shown) and may be supported upon the gas-fixture 6, as shown in Fig. l, in which case the gas may be utilized for heating the vaporizer in starting the lamp. For this purpose the fitting 5 is provided with an oil-passage 40 and with a gas-passage 4l, with which latter connects a pipe 42, having its upper end encircled about the vaporizer and provided with gas-outlet perforations 43.

I prefer to make the gas-outlets o for the heating-jet in the tube b below the Wall h; but they may be made in the wall h instead, and while this latter construction is good I do not deem it as efficient as the construction shown.

The tube d forms a wind-shield for the heating-jet and a chimney for the dame from the alcohol-cup 35 when the latter is used for starting the lamp.

By reference to Fig. l it will be seenl that the vapor issuing from the vaporizer is cornmingled with fresh air near the dischargeorifice of said vaporizer and that this mixture is caused to pass through a series of chambers before it finally reaches the point Where it is consumed, and as a result the said mixture is commingled in a most eflicient manner, which serves to insure a proper combustion, and thus increases the efficiency of a lamp of this class. The mantle t may be supported above and in line with the outletmouth of the burner, as herein shown, by a rod or arm 50, adjustably secured by setscrew 51 to a stud or arm 52 on a ring or collar 53, fitted over the upper portion of the IOO IIO

vas

tube b. The irregular course throughwhich the vapor vpasses on its way through the burner acts to deaden the sound, so that noise is reduced to a minimum, which is very desirable in lamps of this character.'
